Abstract

L’invention concerne un viseur optronique (2) pour engin motorisé tel qu’un véhicule aérien ou marin propulsé par hélice, ou un véhicule terrestre chenillé comprenant un module de visée (4), des moyens de déplacement (17a, 17b) du module de visée autour du premier (8a) et du second axe (10), des moyens de mesure (14) en continu d’une donnée angulaire, caractérisé en ce qu’il comprend une boucle d’asservissement comprenant des moyens de mesure en continu de l’accélération (28) du module de visée (4) selon trois directions orthogonales de l’espace (8a, 8b, 8c), des moyens de détection (32) d’au moins une fréquence fondamentale des perturbations vibratoires, un correcteur adaptatif (26) configuré pour recevoir continument en entrée ladite fréquence fondamentale, un écart entre une valeur de consigne angulaire et ladite donnée angulaire, fournir en sortie une valeur de consigne de déplacement aux moyens de déplacement (17a, 17b). Figure à publier avec l’abrégé : Figure 3The invention relates to an optronic sight (2) for a motorized vehicle such as an air or marine vehicle propelled by a propeller, or a tracked land vehicle comprising a sighting module (4), means of movement (17a, 17b) of the module sighting around the first (8a) and the second axis (10), means (14) for continuously measuring an angular datum, characterized in that it comprises a servo loop comprising means for continuously measuring acceleration (28) of the sighting module (4) along three orthogonal directions in space (8a, 8b, 8c), detection means (32) of at least one fundamental frequency of the vibrational disturbances, a corrector adaptive device (26) configured to continuously receive as input said fundamental frequency, a difference between an angular setpoint value and said angular datum, supply as output a displacement setpoint value to the displacement means (17a, 17b).
